Abstract

A field emission display includes corrugated insulating support pillars (96) disposed between the phosphorous layer (95) and the substrate (50) for reducing arcing between the cathode (92) and the anode (93) along the surface of the pillar. The corrugation of the insulating support pillars provides for a substantially increased operating voltage between the cathode and the anodes thereby increasing the operating life and efficiency of the field emission display.
